____ [38]3 years ago
5 0
When we have power function or exponential, or then we have a/x, then functions are not going to give arithmetic sequence, because an arithmetic sequence it is really a linear function  when x are natural numbers,

so we need to check  only A
<span>f(x)=- x/3 +5
 
x  1             2               3              4              5
y 14/3      13/3         12/3        11/3        10/3           arithmetic difference is -1/3

so the answer is A</span>

Can someone help me asap <br>I attempted to do it so just ignore that part ​

Answer:

a = 180° -73°

b = 73°

c = 180° -73°

Step-by-step explanation:

73° and b are vertical angles, so are congruent (equal).

a and c are equal to each other and each is a linear angle with 73°, so is the supplement of that angle. You could write the equation as ...

a + 73° = 180°

but I prefer to get to the heart of it. The values of a and c are the difference between 180° and 73°.

Ilia_Sergeevich [38]
D is answer.
Perimeter is 2x +3x +2x + 3x = 10x where x is unknown factor of distance.
So P = 10x
Velocity is 12 km/hr = .2 km/min
P =1.6 Km = 10x
x= .16 Km 3x = .48 km, 2x=.32 km
Area = .48 X .32 Km^2
= 153600 m^2

Answer:

T = total #

T = 5 (to the aunt) + 1/2 (T - 5) (to his friends) + 1 (to his sister) + 4 (left)

T = 5 + 1/2 (T - 5) + 1 + 4

T = 10 + 1/2 (T - 5)

2T = 20 + (T - 5)

2T = 20 + T - 5

2T = 15 + T

T = 15
